driver model: reinstate bus iterators.
This replaces the bus iterators bus_for_each_dev() and bus_for_each_drv().
Though no one in the kernel was using these, the MCA bus updates that are
about to appear depend on them.
They both now take a start pointer, which is the item to begin walking
the list from, if it is not NULL.
